Most Important Exam Questions

Q. 01
The area of the plan of an old map plotted to a scale of 10 meters to 1 cm measured 100.2 cm² when measured by planimeter. The map is shrunk so that a line originally 10 cm long measures 9.7 cm only. Further, the 20 m chain used was 8 cm too short. Find the true area on the ground?
Q. 02
What is tape correction? Explain its different types in detail.
Q. 03
What is the difference between correction and error in surveying?
Q. 04
What is testing of a chain? Why is it necessary before field survey?
Q. 05
A 20 m tape is held 40 cm out of line. Find the resulting error in measurement?
Q. 06
Define the following survey terms (4 Marks Fix):
Survey Line Chain Line Main Survey Line Base Line Tie or Subsidiary Line Check Line
Q. 07
Prove that the incident ray is perpendicular to the emergent ray in an optical square.
Q. 08
What is the principle of chain surveying? Explain working from whole to part.
Q. 09
What are the causes of magnetic declination and its variations?

Q. 10

The following bearings were taken in running a closed compass traverse:

Line	Fore Bearing (F.B.)	Back Bearing (B.B.)
AB	124° 30'	304° 30'
BC	68° 15'	246° 00'
CD	310° 30'	135° 15'
DA	200° 15'	17° 45'

At what stations do you suspect local attraction? Find the corrected bearings of the lines and compute the included angles.

Q. 11
Explain the temporary adjustments of a prismatic compass in sequence.
Q. 12
The following staff readings were observed successively with a level, the instrument having been moved forward after the 2nd, 4th, and 8th readings:
0.875, 1.235, 2.310, 1.385, 2.930, 3.125, 4.125, 0.120, 1.875, 2.030, 3.765

The first reading was taken with the staff held upon a Bench Mark (BM) of elevation 132.135 m. Enter the readings in a level field book and reduce the levels by either method. Apply the arithmetic checks and find the difference in elevation between the 1st and last points.
Q. 13
Comparison between Height of Instrument (H.I.) method and Rise & Fall method.
Q. 14
What is levelling? Explain its various types and field applications.
Q. 15
Define the following contour terms:
Contouring Contour Interval Horizontal Equivalent Contour Gradient
Q. 16
Define surveying. Explain its primary classifications and secondary types briefly.
Q. 17
What are the key differences between Plane Surveying and Geodetic Surveying?
Q. 18
State the primary objects and fundamental principles of surveying in detail.
Q. 19
What are the different kinds of chains used for linear measurements? Explain their lengths and link counts.
Q. 20
Explain the direct and indirect stepping methods of chaining on sloping ground.
Q. 21
What is tape correction? Write down the formula for pull, temperature, and sag corrections.
Q. 22
What is ranging? Describe the field procedure for direct and reciprocal ranging.
Q. 23
Explain the procedure for testing a chain and methods of adjusting an incorrect chain.
Q. 24
Numerical Problem on Chain/Tape Errors (10 Marks Fix): Calculation of incorrect length, true distance, and true area.
Q. 25
Explain the fundamental principle of chain survey: "Working from whole to part" and "Fixing a point by at least two reference measurements".
